When driving down a long slope, relying solely on the braking system can easily cause it to fail.

ANSWER · A

Car brakes are of three types: 1. Service brakes, the foot pedal that controls all four wheels; 2. Parking brakes, the handbrake that prevents the car from rolling when parked; 3. Engine braking, used when service brakes fail. The driver shifts down one gear at a time, using engine and gearbox drag to slow the car. On a long descent, prolonged use of service brakes causes brake fade and reduced braking efficiency.
